ABSTRACT

A new and distinct  Citrus Reticulate Blanco  plant named ‘Tamdo No. 3’, characterized by its upright plant type and strong vigor, The plant type of Tamdo No. 3 is upright and the tree vigor is strong, fruit shape is oblate and the fruit shape index is about 143, fruit skin thickness is about 2.7 mm so it is easy skinning, the fruit flesh rate is about 82.9%, sugar of fruit juice is about 13.7° Bx, the acidity is about 0.79%, and the sugar acid ratio is about 17.34.

Latin name of the genus and species of the plant claimed: Citrus reticulata Blanco.

Variety denomination: ‘Tamdo No.3’.

BACKGROUND OF THE INVENTION

The new and distinct cultivar is a product of a breeding program by the inventors by cross a Japanese variety ‘Kiyomi’ and an American variety ‘Sunburst’ mandarin (as the pollen parent) was carried out. The seeds obtained by the cross were sowed in the next spring. The plants started fruiting in 2010. In 2011, the first screening was carried out, and the one called Jegamna-27 was selected. In the last screening which carried out in 2012, Jegamna-27 was selected as an office upbringing new variety and named ‘Tamdo No.3’.

After Hybridization of the parents, the variety was planted by asexual propagation for three generations and there was no genetic variation, therefore its traits are stable.

The fruit characteristics of Tamdo No.3 are in the Table 1 below. The test carried out from 2010 to 2012, in Citrus Research Station.

SUMMARY OF THE INVENTION

The cultivar ‘Tamdo No. 3’ has not been observed under every possible environmental conditions. Therefore, there may be variations in the phenotype due to varying environmental conditions such as temperature, day length and light intensity. However, the genotype will not vary.

The following trait have been repeatedly observed and are determined to be in the characteristics of the new cultivar of Citrus Reticulata Blanco. These attributes in combination distinguish ‘Tamdo No. 3’ as unique from and all other varieties of Citrus reticulate Blando know to inventors.

1. The plant type of Tamdo No.3 is upright and the tree vigor is strong.

2. The fruit color is orange.

3. Germination stage of Tamdo No.3 is in the middle of April, and the blooming stage is in late May.

4. Fruits start coloring in late October and finish coloring in early December.

5. The mature stage is in the middle of February.

6. Fruit shape is oblate and the fruit shape index is about 143.

7. Fruit skin thickness is about 2.7 mm so it is easy skinning.

8. The fruit flesh rate is about 82.9%.

9. Sugar of fruit juice is about 13.7° Bx, the acidity is about 0.79%, and the sugar acid ratio is about 17.34.

Plants of the new cultivar ‘Tamdo No. 3’ are similar to plants of the seed parent ‘Kiyomi’ in most horticultural characteristics, however, the plants of the new cultivar ‘Tamdo No. 3’ produce tree vigor that are stronger than the parent. Compared to the parent, ‘Tamdo No. 3’ produces fruit with skin thickness of about 2.7 mm. The fruit surface of the new cultivar is smooth, whereas the ‘Kiyomi’ cultivar has a rough fruit surface.

The new cultivar differs from the closest comparable plants and characteristics of the new cultivar as shown in the tables below:
